green cooling initiative: TNV

The Natural VoiceTNV

The Natural Voice is a global call for action supported by industry and other parties that points to the environmental, economic and social potential of natural refrigerants in heating, cooling & refrigeration.

The Natural Voice statement will be presented to National Governments and International Climate Negotiators to acknowledge the ecological, economic, and social benefits of CO2, ammonia, hydrocarbons, water, air and other natural refrigerants. It sends a positive message to industry, legislators and individuals looking for future-proof heating, refrigeration and air-conditioning solutions to the climate crisis we are facing.

The Natural Voice project will build on this statement to develop actionable initiatives around the world.

The more Organisations add their own voice to The Natural Voice, the stronger it will grow. It is open to industry, associations, non-profit organisations, and any other party or individual supporting its values.

The GCI is a signatory of The Natural Voice and supports the call for acknowledging natural refrigerants as ecological, economic and social beneficial solutions for the RAC sector.


The GCI is funded by the International Climate Initiative by the German Federal Ministry for the Environment, Na­ture Conservation, Building and Nuclear Safety (BMUB) and implemented by GIZ Proklima.
